Doctor Victor Von Doom may be a merciless despot who craves nothing less than total world domination. However, Doctor Doom also insists that the children of his country Latveria live in joy and safety, so the image that Robert Downey Jr. posted on Easter Sunday isn’t entirely out of character with the villain he’s playing in Avengers: Doomsday. The post features art by an unattributed artist showing Doom holding a basket full of eggs, each of which has a superhero’s logo.

For the most part, the logos all match characters we expected to be in Doomsday ever since Marvel slowly announced the cast with a video about chairs last year: there’s the X-Men, Fantastic Four, Shang-Chi, Namor, Loki, etc. However, those looking closely also notice the logo of a hero who has NOT been confirmed, that of Spider-Man.

The lack of Spider-Man has been a glaring omission in the Doomsday cast so far. Not only is Spider-Man, far and away, the most popular superhero around the world, but he played an integral role in the last major Avengers movies, Infinity War and Endgame. Moreover, Spider-Man: Brand New Day comes to theaters just months before Doomsday, which means that something in that movie will certainly relate to the events of the later film.

And yet, there’s been no word about ol’ web head joining the Avengers, the X-Men, or the Fantastic Four against Doctor Doom.

Well, no official word, that is. Unofficially, leakers have long reported that Doomsday will begin with a scene that sees Cyclops, Magneto, and other members of the X-Men from the 20th Century Fox movies battling against Tobey Maguire as Spider-Man.

Why would these heroes fight one another? Outside of Spidey’s established and well-earned frustrations with the X-Men, the fight reportedly involves the central premise of Doomsday. The Fox X-Men universe and the Maguire Spidey universe are experiencing an Incursion, a multiversal event in which one universe collides with another. For reasons not yet clear, but they probably involve Doom’s manipulations, the heroes are both trying to defend their own Earth by destroying the Earth of the others.

The plot point comes directly from the lead-up to the Secret Wars storyline in the comics, in which Reed Richards, Black Panther, Iron Man, and other powerful figures in the Marvel Universe banded together as the Illuminati to find a way to stop the Incursions. In their darkest and most desperate moment, the Illuminati destroyed other Earths to save their own.

Will the Maguire Spider-Man be forced to make a similar choice? Or will other Spideys, perhaps played by Andrew Garfield, Tom Holland, or, dare we hope for it, Nicholas Hammond be involved?

We won’t know for sure until Doomsday hits theaters later this year. Because Doom may suffer the games played by children, but Doom will suffer no untimely spoilers.
